Teacher's union rep: "We will not stand for any cuts in our benefits or salaries. Even if we make six figures with guaranteed employment regardless of performance. Even if the state is on the verge of bankruptcy. Why? Because this is about social justice"

A Utopian fantasy based on the Leninist concept of "equality of outcome." It says that since you have more, it must be taken away from you to give to those who have less, so that you are both equal. So there is much in common with the petty thief, who steals your wallet at gun point in order to equalize both of your wealth. Though this never seems to apply to rulers, who always seem to be exempt from social justice policies.

In order for social justice to exist, there has to be a ruling class to mete out that social justice. If there is an elite ruling class, then there is no social justice. So the concept of social justice always collapses in upon itself.

Social Justice is generally supported by hipsters of all ages who can't afford weekly groceries or gas for their cars, but who are simultaneously bedazzled with hundreds and sometimes thousands of dollars of tattoos and piercings.

It is often used by power hungry despots to fool voters into surrendering their rights and liberties in exchange for promises of free stuff, while lining the pockets of the ruling class with the stolen wealth of the people.

They promised social justice in Venezuela. They can't even supply toilet paper. Meanwhile, Maduro's right hand man Aristóbulo Istúriz has over $9.6 million in a Swiss bank account. At least Chavez's daughters still get to live it up in the Presidential Party Palace, La Casona.

In the Ukraine where the average salary is less than £300 a month, President Viktor Yanukovych said that 2013 would be a year of social justice. In 2014, the Ukrainian people found that his personal estate which was half the size of Monaco, contained a 5 floor mansion, a golf course, a private zoo, a park, a greenhouse, a garage filled with luxury sports cars, a helicopter pad, a pirate ship which served as a personal restaurant, a hovercraft, etc.

In America, they promised free healthcare for everyone. Now it costs more, and I have less coverage. I hear the First Ladies' newest dress cost $12,000. That's social justice for ya.

Word used mainly by American teenagers and those without a college education to describe the frustration they feel at their own failures in life.
Most of these individuals don't feel the need to get an official definition of this word to see if they believe in equality of opportunity for example, rather they will go to tumblr or find an extreme feminist vlog and confuse social justice with other disturbed individuals who abuse the concept for their own personal gain.

Social justice is ruining gaming
Social justice is communist
Social justice is feminism

The (typically online) practice of preaching for equality for people of all religions, races, genders, and sexual orientations. When done right, this can be a fantastic thing. Unfortunately, social justice tends to be done wrong, giving things like the gender equality movement and the gay rights movement a bad name.
